SEEGIFLCATION forming part of Letters Patent No. 735,564, dated August4, 1903.

Application filed April 2, 1902. Serial No. 101,101. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM L. MCCABE,

a citizen of the United States, residing at Seattle, in the county ofKing and State of Wash-' ington, have invented certain new and usefulImprovements in Portable Oonveyers; and I do hereby declare thefollowing to be a full,

clear, and exact description of the invention;

such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in portable conveyers, and theobject in view is the production of a compactly-constructedconveyerprovided with means for facilitat veyer-frame being indicated in dottedlines.-

Figs. 4. and 5- represent enlarged detail views of the supporting-spoolwith surrounding parts. Fig. 6 represents a View in top plan of thedischarge-chute with its guiding-shield,

the conveyer being partially broken away.- Fig. 7 represents a view ofthe same in side elevation. Fig. 8 represents a fragmentary perspectiveView of the shield and surroundand to employ means for enabling the ready transportation of the entire structure. In order to attain these andother similarly dcsirable ends, I employ a suitable conveyerframework,as l, of well-known construction, having one end pivoted, as at 2; toany suitable platform, as 3, said platform preferably consisting ofparallel angle-irons secured together by suitable'cross-pieces, theplatform being formed-in two lengths, one of slightly less widththan theother, the narrower length being arranged to slide longitudinally withinthe Wider, whereby'a telescoping action of the parts may be produced.The telescoping sections are preferably held in position rela- I tive toeach other by bolts or pins passed through a longitudinal slot in oneangle-iron and secured to the contiguous iron.

The inner pivoted end of framework 1 supports platform 3, and the outerend of said platform is preferably supported by suitablerotatably-mounted casters, as 4, eachhaving a shackle, as 5, secured toits axle (5, said shackle being provided with an integral arm, as 7,carrying a turnbuckle, as 8, which turnbuckle is threaded onto asuitable rod 9. The rod 9'detachably engages the platform 3, as at 10,whereby the casters 4 will be held in a fixed position duringtransportation of the conveyer upon the casters, but may be turned to anangle to their normal plane when it is desired to move the conveyerlaterally.

As best seen in Fig. 9, a collar, as 11, surrounds each side angle-ironof platform 3, each collar beingprovided with an eye, as 12, said eyesbeing connected by rods 13.13, threaded at their inner ends into aturnbuckle, as 1 1.

Mounted on the transverse horizontal braces of platform 3 is a motor, as15, of any suitable and preferred type, carrying any desired drivingmeans,-as a pulley 16, normally extending beyond one of the longitudinalangleirons of platform 3. The end of motor 15 opposite that carryingpulley 16 preferably lies in a vertical plane a sufficient distanceinside its contiguous longitudinal angle-iron to permit of saidpulley'l6 being brought inside the vertioal plane of its correspondinglongitudinal angle-ir0n by a lateral adjustment of the motor. The motor15 is also mounted to slide longitudinally of platform 3, and suitablewinding-drums, as 17 and 18, are arranged at or near the ends of saidplatform and connected .by cables with said motor for adjusting the sameto any desired position.

As best seen in Figs. 3 and 9, I preferably form an auxiliarylaterally-projecting platform, as 19, integral with or connected to ICOplatform 3 in any preferred manner, and my object is when desired tolift the motor bodily and place the same in operating posi tion upon thesaid platform 19. A second auxiliary platform, as 20, is supported upona frame extending upwardly from and in the same vertical plane withframework 1 for receiving the motor 15, as indicated in dotted lines inFig. 1, the supporting-beams of said frame being preferably connected tothe sides of said framework 1 for permitting the articles conveyed to bepassed thorebetween.

Mounted upon platform 3, near the castersupported end thereof, are twopair of standards, as 21 21, one pair 011 each side of the platform, thestandards of each pair being spaced apart, the outer being braced by abracket, as 22, and the inner hinged, as at 23, the upper ends of therespective standards being secured together by a strap, as at 24, towhich is attached the upper end of a brace 25. The lower end of brace 25is removably connected with platform Between said standards extends ashaft, as 26, carrying a spool 27 and having grooved pulleys, as 28 2S,fixed to its ends. The lower ends of the pairs of standards 21 arepreferably braced in any suitable manner, as by transverse bars 29. Ashaft, as 30, is arranged above platform 3 and carries a winding-drum,as 31, at each end thereof, suitable means, as a ratchetwheel 32,designed to be engaged by a pawl 33, carried by an operating-lever 34,being provided for rotating shaft 30 and its drums. Each pair ofstandards 21 carries brackets 35, in which are revolubly mounted theshaft of a grooved pulley, as 36. Each pair of standards 21 has a cable,as 37, fixed near the upper end thereof and extending downwardly aboutits respective pulley 28, passed upwardly about its respective pulley36, and again passed downwardly and secured to its respective drum 31.It will now be apparent that rotation of drums 31 in one direction willtend to raise shaft 26 and spool 27, and rotation of said drums in anopposite direction will lower said parts, thecables 37 being of asufficient length to permit shaft 26 and spool 27 to be lowered anydesired distance. The framework 1 carries suitable drums, as 39 and 40,at the ends thereof for supporting a carrier-belt, as 41, the said beltin operation moving about drum 39 longitudinally of framework 1 andabout drum 40. It next passes about a driving-drum, as 42, and is lappedupon itself in an opposite direction to that of its return movement,passes about a tension-drum 43, and then passing onward to and aboutdrum 39, that part of the return of the belt between drum 43 and drum 39lying approximate the upper portion of the belt, whereby the lowerportion of framework 1 is left vacant for purposes hereinaftermentioned. The drum 43 may be provided with any suitable means formoving the same laterally longitudinally of the framework,whereby theamount of lap in the return portion of belt 41 may be increased ordecreased for controlling the tension of the belt.

A shaft, as 44, extends transversely through framework 1, carrying adriving-pulley, as 45, at one end and a smaller pulley (not shown) atthe other, the former pulley being driven by a belt 46, receiving motionfrom pulley 16, and the latter pulley imparting motion through a belt,as 47, to a pulley 48, fixed to a shaft 49,carrying drivin g-d rum 42. Alever, as 50, is pivoted, as at 51, to framework 1 and carries twoidler-pulleys, as 52 and 53, spaced apart and designed to engage therespective portions of belt 46 for regulating the tension thereof. Thelever 50 may be of the elbow type and, if preferred, may carry asuitable weight at its free end.

It willreadily appear from the drawings that theframework 1 rests uponspool 27 and that the open space in said framework left by theparticular arrangement of the driving-belt is designed to register withmotor 1.5 for inclos- 'ing the same when the framework is loweredsufficiently.

In operation it is often found desirable to permit the upper end offramework 1 to rest upon the ship to which articles are being conveyed,and in such instances a guiding-chute, as 54, is preferably connected tosaid end of the framework and usually arranged at right angles thereto.An arm, as 55, is pivoted to the upper end of the framework, and asecond arm, as 56, is pivoted beneath the same, the former preferablynormally extending in a horizontal plane and the latter being providedwith a series of apertures, as 57, and extending in a diagonal planeacross the former, the two being preferably secured together by a pinpassed through a given aperture 57 and a suitable aperture in arm 55.The apertures 57 permit of vertical adjustment of arm 55. The upper endof chute 54 rests upon arm 55, and a slot, as 58, is formedlongitudinally of said chute, near that edge thereof nearest theframework 1, and a pin, as 59, carried by said framework, extendingthrough said slot for retaining the chute against lateral movement, butleaving the same free to swing up and down with the movement of thevessel upon which it rests. A standard, as 60, extends upwardly fromchute 54 and is secured to a guiding-shield, as 61, for retaining saidshield in position, the said shield consisting of a sheet of suitablematerial curved from the point at which it is attached to standard 60,which lies in line with one edge of belt 41, to a point on the oppositeside of the chute lying in line with the opposite edge of said belt. Astandard, as 62, is pivotally attached to arm 55 to swing transverselyof said framework, but held against lateral movement in the longitudinalplane of said frame. The upper end of standard 62 engages shield 61 nearthe upper edge thereof by means of a bolt passed through a segmentalslot, as 63, in said shield.

It will now be apparent that articles con- IIO veyed by belt 41 will bedirected against shield 61, which will guide the same at a right angleto their former movement and down chute 54. Any vertical movement ofsaid chute will be accommodated by pin 59, with its slot 58, and by thepivotal attachment of standard 62, the vertical movement of the upperend of framework 1 being taken up by said pin-and-slot connection and bythe segmental slot 63.
